  • Page 5: Safety Instructions And Measures

    SAMSON does not assume any liability for damage resulting from the failure to use the de- vice for its intended purpose or for damage caused by external forces or any other external factors.
  • Page 6 Î Observe safety measures for handling the device as well as fire prevention and explosion protection measures. Safety features The Types 46-7, 47-5 and 47-1 Regulators do not have any special safety features. When relieved of pressure and with open restriction, the regulators are opened by the force of the set point springs. Responsibilities of the operator Operators are responsible for proper use and compliance with the safety regulations. Opera- tors are obliged to provide these mounting and operating instructions as well as the refer- enced documents to the operating personnel and to instruct them in proper operation.
  • Page 7 Start-up and shutdown procedures fall within the scope of the operator's duties and, as such, are not part of these mounting and operating instructions. SAMSON is unable to make any statements about these procedures since the operative details (e.g. differential pressures and temperatures) vary in each individual case and are only known to the operator.

  • Page 9 Safety instructions and measures WARNING Risk of personal injury due to incorrect operation, use or installation as a result of in- formation on the regulator being illegible. Over time, markings, labels and nameplates on the regulator may become covered with dirt or become illegible in some other way. As a result, hazards may go unnoticed and the necessary instructions not followed.
  • Page 10: Notes On Possible Property Damage

    Î Wear protective clothing and safety gloves. Damage to health relating to the REACH regulation. If a SAMSON device contains a substance listed as a substance of very high concern on the candidate list of the REACH regulation, this is indicated on the SAMSON delivery note.
  • Page 11 Risk of regulator damage due to the use of unsuitable lubricants. The lubricants to be used depend on the regulator material. Unsuitable lubricants may corrode and damage surfaces. Î Only use lubricants approved by SAMSON. When in doubt, consult SAMSON. EB 3131 EN...
  • Page 12 Risk of regulator damage due to the use of unsuitable tools. Certain tools are required to work on the regulator. Î Only use tools approved by SAMSON. When in doubt, consult SAMSON. Risk of the process medium being contaminated through the use of unsuitable lubri- cants and/or contaminated tools and components.
